Systems and method for creating transmural lesions
First Claim
1. An ablation system for treating tissue within a body organ, comprising:
- an ablation source having a power terminal and a return terminal;
an ablation probe electrically coupled to the power terminal of the generator, the ablation probe including an ablation element; and
a ground probe electrically coupled to the return terminal of the generator, the ground probe configured to be inserted within the body during use;
wherein one of the ablation probe and the ground probe is configured for being intravascularly introduced to an interior of the organ, and another of the ablation probe and the ground probe is configured for being extravascularly placed in contact with an exterior of the organ.

Abstract
An ablation system includes an ablation source, an ablation probe having an ablation element coupled to a power terminal of the generator, and a ground probe coupled to a return terminal of the generator, the ground probe configured to be inserted within a body during use. One of the ablation probe and the ground probe is configured for being intravascularly introduced to an interior of an organ, and another of the ablation probe and the ground probe is configured for being extravascularly placed in contact with an exterior of the organ. A method of ablating tissue having a thickness includes placing one of an ablative element and a ground element in a first location adjacent the tissue, placing another of the ablative element and the ground element in a second location adjacent the tissue, and delivering ablation energy through the thickness of the tissue between the ablative and ground elements.
